If at the time when the Grīṣma season just comes to a close, the north wind should blow charged with the odour of the fragrant flowers of the Kadamba tree, the Earth will be covered with water from clouds whose various hues will appear beautiful by the light of lightning, the Moon being invisible at the same time.
